Codemasters has sent over the launch trailer for DiRT Showdown, which launches on PS3, Xbox 360 and PC tomorrow in the UK. The launch video showcases the maximum-impact racing, bone-rattling destruction game modes, freestyle Hoonigan events and multiplayer party games set to take centre stage on DiRT Showdown's World tour of motorised mayhem. From Miami to LA and San Francisco to Yokohama, the trailer features drivers taking down their rivals, boosting to overtake, hitting jumps and performing stunts as they go for the win across DiRT Showdown's wide range of game modes.
